Answer:
f(5) =7
Step-by-step explanation:
According to the graph,
since y=f(x) thus means the value of y when x=5
the answer is 7
The graph is decreasing then increasing function when the graph is given in the picture.
Given that,
In the picture there is a graph.
We have to find is the graph is increasing or decreasing.
We know that,
<h3>What is the increasing and decreasing function?</h3>
Moving towards the right side of the x-axis causes the graphs of increasing and decreasing functions to move in the opposite directions. Other names for rising and decreasing functions include non-increasing and non-decreasing functions.
So,
From the graph we can say
The graph is decreasing then increasing function.
Therefore, The graph is decreasing then increasing function when the graph is given in the picture.

Complete question :
A data set includes data from student evaluations of courses. The summary statistics are nequals92, x overbarequals4.09, sequals0.55. Use a 0.10 significance level to test the claim that the population of student course evaluations has a mean equal to 4.25. Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim.
Answer:
H0 : μ = 4.25
H1 : μ < 4.25
T = - 2.79
Pvalue =0.0026354
we conclude that there is enough evidence to conclude that population mean is different from 4.25 at 10%
Step-by-step explanation:
Given :
n = 92, xbar = 4.09, s = 0.55 ; μ = 4.25
H0 : μ = 4.25
H1 : μ < 4.25
The test statistic :
T = (xbar - μ) ÷ s / √n
T = (4.09 - 4.25) ÷ 0.55/√92
T = - 0.16 / 0.0573414
T = - 2.79
The Pvalue can be obtained from the test statistic, using the Pvalue calculator
Pvalue : (Z < - 2.79) = 0.0026354
Pvalue < α ; Hence, we reject the Null
Thus, we conclude that there is enough evidence to conclude that population mean is different from 4.25 at 10%
Answer:
90°
Step-by-step explanation:
Whenever you are required to transfer from Radians to Degrees, simply multiply the Numerator by 180° (180). Treat the 
as a variable such as x and y, and divide by the numerator.
